Bias current source, low-noise amplifier and comparator for superconducting nanowire detectors with latch detection and automatic bias reset.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| det_in | in | analog | 4 | |
| click_out | out | parallel | 4 |
